Isakhiwo Sensimbi se-ASTM A992, A572, A283, A913: Umehluko Obalulekile Emakethe Yesakhiwo Sensimbi Yomhlaba Wonke

Namuhla, ukukhetha izinga elifanele lensimbi kubalulekile ekuqineni kwesakhiwo, ekukhiqizweni, kanye nezindleko zephrojekthi iyonke embonini yokwakha. Ngaphansi kwezindinganiso zaseMelika kunezinga ezine ezivamile zensimbi.insimbi yesakhiwo i-ASTM A992, A572, A283 kanye ne-A913ngayinye yalezi zinsimbi inamazinga ahlukene okusebenza kanye nezidingo zephrojekthi.

Umehluko Wezinto Ezibonakalayo Nezomshini

I-ASTM A992
Isigaba: Insimbi yesakhiwo enamandla aphezulu e-low-alloy (HSLA)
Ukucindezeleka okuncane: 345 MPa (50 ksi) amandla okukhiqiza
Isici: Ukwakheka kwezinto ezisetshenziswayo ze-weld “umenzi we-weld kanye nezinto ezisetshenziswayo ze-weld ezihlobene nokucindezeleka” kulawulwa ngokuqinile ukuqinisekisa ukuvumelana nokuqina.
Ifomu Eliyinhloko: Yenzelwe ngqo i-hot roll wide flange (i-W/H beam).
I-A992 iyinsimbi ejwayelekile enamandla aphezulu eNyakatho Melika yokwakha insimbi yohlaka.

I-ASTM A572
Isigaba: Insimbi yesakhiwo enamandla aphansi (i-HSLA) enamandla aphezulu
Amabanga: 42, 50, 55, 60, 65
Izinga lamandla: Kukhulu kunensimbi yekhabhoni evamile.
Okuphakelwayo: Amapuleti, ama-engeli, iziteshi, imisebe nokuningi
Amabanga aphansi (iBanga 42,50) angashintshwa ngezinqubo ezijwayelekile zokushintshwa, Amabanga aphezulu (iBanga 65) adinga izinqubo ezikhethekile zokushintshwa noma ukuhlolwa okwengeziwe njenge-PWHT njll.

I-ASTM A283
Uhlobo: Insimbi yesakhiwo sekhabhoni (insimbi ethambile)
Amabanga: ABCD = Iyatholakala
Amandla: Buthaka kune-A572 ne-A992
Ungasho ukuthi kwakufana nokwakha nokushisela indlovu encane ngentengo yendlovu endala.
I-ASTM A283 elula kuphela noma. I-General ASTM A283 yenzelwe ukusetshenziswa nezakhiwo ezingezona ezibucayi.

I-ASTM A913
Uhlobo: Insimbi enamandla aphezulu ene-alloy ephansi ngendlela ye-QST (yokucima nokuzithulisa)
Amabanga: 50, 65, 70 = Ayatholakala
Isici: Amandla amakhulu, ukuqina okuvelele kanye nokushibilika okuhle ensimbini enamandla kakhulu.
Ifomu Eyinhloko Yemisebe yeflange ebanzi Ejiyile Nenzima
I-A913 isetshenziswa kakhulu lapho izingxenye ezinamandla aphezulu kanye nezingxenye ezithambile zibalulekile ezakhiweni ezinkulu nezinde ezinqunywe ngensimbi.

Umehluko Wohlelo Lokusebenza

I-ASTM A992
Izakhiwo zensimbi nezentengiselwano zezindlu
Amafreyimu ezakhiwo ezinde neziphakathi nendawo
Izakhiwo zezimboni nezokusabalalisa
Isizathu: Ingathenjelwa ngokuphephile futhi ishiselwe kalula, isetshenziswe emzimbeni wemoto.

I-ASTM A572
Amabhuloho
Amafektri
Izakhiwo zemibhoshongo kanye namandla
Amapulatifomu aqinile
Isizathu: Onjiniyela bokuklama bangenza ngcono ibhalansi phakathi kwamandla nezindleko ngamamaki amaningi.

I-ASTM A283
Izakhiwo eziphansi
Amashedi ensimbi alula kanye nama-workshop
Amapulazi nezakhiwo zesikhashana
Izingxenye ezingabalulekile
Isizathu: Kushibhile futhi kulula ukuphatha izinto, kodwa kunamandla amancane okuthwala.

I-ASTM A913
Ama-skyscraper
Amabhuloho amade
Izinkundla zemidlalo kanye namahholo okuhweba
Amaphrojekthi amakhulu ezimboni
Isizathu: Amalungu amancane kanye nobude obude kungatholakala ngamandla aphezulu kakhulu.

Imakethe kanye Nokuthandwa Kwesifunda

Isakhiwo Sensimbi se-ASTM A992: Itholakala e-United States naseCanada, eMpumalanga Ephakathi, eNingizimu-mpumalanga ye-Asia yohlaka lwesakhiwo.

Isakhiwo Sensimbi se-ASTM A572: Kukhethwa kakhulu eSigabeni saseMelika kanye nasezifundeni ezigxile kwingqalasizinda ezifana namabhuloho kanye nezakhiwo ezisindayo.

Isakhiwo Sensimbi se-ASTM A283: Isetshenziswa kabanzi ezweni lesithathu ekwakheni okungabizi kakhulu nokulula.

Isakhiwo Sensimbi se-ASTM A913: Isetshenziswa kakhulu emazweni athuthukile kanye nasezindaweni ezinkulu zamaphrojekthi njenge-USA, iYurophu, iMiddle East, ne-East Asia.

Izindleko kanye Nezomnotho Ezicatshangelwayo

A283: Intengo ephansi kanye nekhwalithi ephansi

I-A992: Izindleko eziphakathi nendawo, ibhalansi enhle yamandla kanye nokulula kokwenziwa

A572Izindleko zincike ebangeni

I-A913: Izindleko eziphezulu kakhulu ngeyunithi ngayinye, kodwa amandla aphezulu anciphisa inani lensimbi eliphelele

Izinsimbi ezinamandla aphezulu zinganciphisa izindleko zephrojekthi ngokunciphisa inani lezinto zokwakha, ezokuthutha kanye nokufakwa kwazo.

Ukukhiqiza Nokushisela

A283: Kulula ukusika nokushisela

I-A992: Yakhelwe ukushiselwa ukuze isetshenziswe ekwakheni

A572: Kungashiselelwa, kodwa kudingeka ukulawulwa okuqinile ukuze uthole amamaki aphezulu

I-A913: Indlela entsha evumela ikhono elihle lokushisela emazingeni aphezulu kakhulu okuqina.

Isifinyezo Nokuqhathanisa

Okujwayelekile Izinga Lamandla Ukusetshenziswa Okuvamile Izinga Lezindleko Izimakethe Ezishisayo
I-ASTM A992 Phezulu Izakhiwo, ozimele Okuphakathi nendawo I-USA, iMpumalanga Ephakathi, iNingizimu-mpumalanga ye-Asia
I-ASTM A572 Okuphakathi–Okuphezulu Amabhuloho, izitshalo Okuphakathi–Okuphezulu Izifunda zeMelika, Ingqalasizinda
I-ASTM A283 Phansi Izakhiwo ezikhanyayo Phansi I-Afrika, iNingizimu Asia, iMelika Ephakathi
I-ASTM A913 Phezulu Kakhulu Ama-skyscrapers, amaphrojekthi amakhulu Phezulu I-USA, iYurophu, iMpumalanga Ephakathi, iMpumalanga Asia

I-ASTM A283, A992, A572 kanye ne-A913 yizigaba ezine zokusebenza kwensimbi yokwakha. I-A283 yenzelwe umnotho, i-A992 iwuhlaka lwesakhiwo oluzenzakalelayo, i-A572 inikeza izinketho eziningi zamandla engqalasizinda kanti i-A913 iyinani elihle kakhulu lezicelo zesakhiwo esindayo nesiphezulu. Amaphrojekthi okwakha akhula ngamandla abangela ukuthuthela okujwayelekile ezinhlotsheni zensimbi ezakhiwe ezinamandla aphezulu emakethe yamazwe ngamazwe.
